This Is What It Looks Like When Dolphins 'Stampede'

Once in a while, very -- very -- rarely, dolphins will abandon their standard serenity and go on a romp that we humans refer to, aptly, as a "stampede." The phenomenon, which involves sub-pods joining together into one splashy social -- and which does indeed resemble the crowd dynamics of wild horses -- is an amazing sight: The creatures, choreographed in a synchronized system that would put our own social networks to shame, leap and churn and leap some more in frenzied-yet-graceful unison.
